Product details

Overview

TSV6392ILT from STMicroelectronics is a dual rail-to-rail input/output micropower operational amplifier in SOT23-8 package, designed for ultra-low-power signal conditioning at supply voltages from 1.5 V to 5.5 V. It delivers 2.4 MHz gain bandwidth product with only 60 µA quiescent current per amplifier at 5 V, 800 µV max input offset voltage (A version), and 1 pA typical input bias current - enabling precision sensor interfacing in battery-powered medical and portable instrumentation.

For engineers reviewing the TSV6392ILT datasheet, TSV6392ILT pinout, TSV6392ILT application, or TSV6392ILT equivalent, key selection criteria include its shutdown capability (5 nA typ ICC in shutdown), EMI hardening (EMIRR up to 92 dB at 1.8 GHz), rail-to-rail operation down to 1.5 V, and guaranteed stability at gains ≥ –3 or ≥ 4 - critical for active filtering and low-voltage analog front-ends.

Technical Context

The TSV6392ILT employs complementary PMOS/NMOS input stages to achieve true rail-to-rail input common-mode range (V_CC– – 0.1 V to V_CC+ + 0.1 V) and rail-to-rail output swing (within 35 mV of rails into 10 kΩ). Its internal compensation ensures phase-margin-stable operation at closed-loop gains ≥ –3 (inverting) or ≥ 4 (non-inverting) with 100 pF load capacitance.

It integrates a dedicated SHDN pin that places both amplifiers into high-impedance shutdown mode with 5 nA typical supply current, 200 ns turn-on time, and logic-compatible thresholds (V_IL = 0.8 V, V_IH = 2 V at V_CC = 5 V). The device is specified across –40 °C to +125 °C and features 4 kV HBM ESD protection and 61–92 dB EMI rejection ratio from 400 MHz to 2.4 GHz.

Key Specifications

Supply Voltage Range	1.5 V to 5.5 V - enables direct operation from single-cell Li-ion, alkaline, or regulated low-voltage rails without level-shifting.
Quiescent Current per Amp	60 µA typ at 5 V - supports multi-year battery life in always-on wearable or IoT sensor nodes.
Gain Bandwidth Product	2.4 MHz typ - provides sufficient bandwidth for DC–100 kHz sensor signals while maintaining micropower efficiency.
Input Offset Voltage (A version)	800 µV max - ensures < 0.1% gain error in 1 V full-scale instrumentation amplifier configurations.
Input Bias Current	1 pA typ - minimizes voltage error across high-impedance pH, photodiode, or piezoelectric sensor interfaces.
Shutdown Current	5 nA typ - reduces system standby power by >10,000× versus active mode, critical for duty-cycled measurement systems.

Operating Temperature	–40 °C to +125 °C - qualified for automotive cabin, industrial edge, and implant-adjacent medical environments.

Pinout & Package

SOT23-8 package: 8-pin ultra-small outline transistor package with 0.65 mm lead pitch, 2.8 × 2.9 mm body, and exposed thermal pad option (not present in standard SOT23-8); suitable for space-constrained PCB layouts in wearables and hearing aids.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT1)	Amplifier 1 output	Delivers rail-to-rail voltage swing; must be decoupled with 10 nF capacitor near V_CC for stability.
2 (–IN1)	Inverting input of Amp 1	High-impedance node (1 pA bias); sensitive to layout-induced leakage and EMI coupling.
3 (+IN1)	Non-inverting input of Amp 1	Accepts common-mode signals from V_CC– – 0.1 V to V_CC+ + 0.1 V - enables direct connection to grounded sensors.
4 (V_CC–)	Negative supply / ground	Reference for all inputs/outputs; requires low-impedance local 10 nF decoupling to minimize PSRR degradation.
5 (+IN2)	Non-inverting input of Amp 2	Independent high-Z input; shares same rail-to-rail CM range as Pin 3.
6 (–IN2)	Inverting input of Amp 2	Matches Pin 2 performance; differential pair transition at V_CC+ – 0.7 V causes minor CMR dip.
7 (OUT2)	Amplifier 2 output	Identical drive capability to Pin 1; capable of sourcing/sinking 40 mA at 5 V (min).
8 (SHDN)	Global shutdown control	Active-high logic input; must be tied to V_CC+ or V_CC– - floating state invalid and may cause erratic behavior.

Key Features

Feature	Design Value
Rail-to-rail I/O	Enables full dynamic range utilization in single-supply 1.5–5.5 V systems - eliminates need for level-shifting or dual supplies.
Micropower + Wide GBW	2.4 MHz bandwidth at only 60 µA per amp - achieves 40 kHz signal fidelity with < 1 µW power per pole in active filters.
EMI-Hardened Architecture	92 dB rejection at 1.8 GHz - prevents RF rectification artifacts in ECG, pulse oximetry, and wireless-sensor nodes.
Low-Voltage Precision	800 µV max V_OS and 2 µV/°C drift - maintains < 0.5% total error over –40 °C to +125 °C in uncalibrated medical transducers.
Robust Shutdown Mode	5 nA shutdown current with 200 ns wake-up - supports sub-second duty cycling in energy-harvesting sensor hubs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar micropower rail-to-rail op amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSV6392IDT	SOT23-8 package, identical electrical specs, but no integrated shutdown function (no SHDN pin).	Used where continuous operation is required and power budget allows ~60 µA per channel always-on.	Select when shutdown control is unnecessary and board space permits same footprint.
TSV6392AIST	MiniSO8 package, A-grade (800 µV max V_OS), same shutdown and AC specs, but larger 3 × 4.9 mm body.	Preferred in designs requiring higher thermal dissipation margin or legacy MiniSO8 footprint compatibility.	Choose for improved thermal resistance (190 °C/W vs. 105 °C/W) or if SOT23-8 assembly yield is marginal.

Compared with TSV6392IDT, the TSV6392ILT adds shutdown control at no cost to precision or bandwidth; versus TSV6392AIST, it trades package size for PCB area savings while retaining identical A-grade offset and EMI performance.

FAQ

What is the minimum recommended gain for stable operation of TSV6392ILT?

The TSV6392ILT is not unity-gain stable. For reliable operation, it requires a minimum closed-loop gain of –3 (inverting configuration) or +4 (non-inverting configuration) when driving 100 pF capacitive loads. This is enforced by internal compensation optimized for micropower efficiency and bandwidth - using lower gains risks oscillation or excessive overshoot.

Does TSV6392ILT support true rail-to-rail input at 1.5 V supply?

Yes. At V_CC = 1.5 V, the input common-mode range extends from –0.1 V to +1.6 V (V_CC– – 0.1 V to V_CC+ + 0.1 V), verified per Table 2 and Figure 19. This allows direct interface with grounded sensors or DAC outputs without level-shifting, even at the lowest rated supply voltage.

How does the SHDN pin behave during power-up?

The SHDN pin must be actively driven high (≥ 2 V at 5 V supply) to enable amplifiers; it is not internally pulled up. During power-up, if SHDN floats or rises slower than V_CC, the device may enter an undefined state. ST recommends tying SHDN to V_CC via a 100 kΩ resistor or controlling it synchronously with the MCU's power-good signal.

Can TSV6392ILT drive a 100 kΩ load with minimal THD+N?

Yes. At V_CC = 5 V, ACL = –10, and f_in = 1 kHz, THD+N is 0.015% into 100 kΩ (Table 6). However, THD increases significantly below 2 kΩ loads due to output stage limitations - the datasheet explicitly recommends R_L ≥ 2 kΩ for low-distortion operation across all supply voltages.
